Don’t wait for a complete breakdown that leaves you without cooling in the Arizona heat. Call Precise Air & Heating right away if you notice any of these common AC problems:
• Strange Noises – Banging, rattling, buzzing, or hissing from the indoor or outdoor unit. These sounds can signal a failing motor or even a refrigerant leak and should be checked right away to avoid a total system failure.
• Warm Air – System is running but blowing lukewarm or hot air. Often caused by low refrigerant levels, airflow issues, or a failing compressor, this is one of the most common "AC not cooling" emergencies we see.
• Frequent Cycling – AC turns on and off more often than usual or struggles to reach the set temperature. Short cycling can be due to a clogged filter, thermostat problems, or an overheating unit and will drive up energy bills if ignored.
• Higher Energy Bills – Sudden spikes in your SRP or APS bill without a change in usage. An AC that’s struggling due to a dirty coil, weak fan motor, or failing components can waste a lot of electricity.
• Weak Airflow or Hot Rooms – Some rooms feel warmer than others, or the airflow from your vents feels low. This can indicate duct issues, blower problems, or a system that’s undersized or aging out.
• Unpleasant Odors – Musty, moldy, or burning smells coming from the vents or unit may point to microbial growth or serious electrical problems and should never be ignored.

This is the most common sign you need immediate repair. If your AC is running but failing to cool your home, the issue is typically serious and may involve:
• Low Refrigerant: A leak in your system means the unit can no longer properly absorb heat.
• Failed Compressor: The compressor is the heart of your system, and if it fails, the cooling cycle stops completely.
• Dirty Condenser Coils: If the outdoor coils are covered in dirt and debris, the unit cannot release the heat it is absorbing, leading to poor cooling performance.
Strange or loud noises are often a warning sign of mechanical failure.
• Banging/Rattling: This may indicate a loose or failing component, such as a fan motor or a broken blade inside the unit. Continuing to run the AC could cause costly secondary damage.
• Hissing/Bubbling: This sound often signals a severe refrigerant leak, which requires immediate attention to protect the environment and restore cooling.
• Buzzing: Usually related to an electrical issue in the outdoor unit or condenser.
When your AC unit starts and stops rapidly without reaching the set temperature, it’s known as "short cycling." This causes excessive wear on your compressor and wastes energy. Common causes include:
• Oversized Unit: If the unit is too large for your space, it may cool the area too quickly and shut off prematurely.
• Clogged Air Filter: A restricted filter can cause the system to overheat and trip a safety switch.
• Low Refrigerant/Freezing: A lack of refrigerant can cause the coil to freeze, causing the unit to cycle off quickly.
If your cooling habits haven't changed but your SRP or APS utility bill has spiked, it usually means your AC system is working too hard to maintain comfort. This is typically due to:
• System Inefficiency: Caused by dirty coils, low refrigerant, or a failing fan motor.
• Air Leaks: Poor ductwork or insufficient attic insulation can force your AC to run constantly.
A professional tune-up or repair can often restore efficiency and lower your monthly cooling costs.
Unpleasant odors from your vents should not be ignored:
• Musty/Moldy Smell: Indicates mold, mildew, or standing water, often caused by a clogged condensate drain line near your air handler.
• Burning Smell: This is usually a serious sign of an overheating motor or burnt electrical wiring, and the unit should be shut off immediately.
